Let's demystify Southwest's baggage allowance, step by step, so you can pack with confidence and stride through the airport like a seasoned pro!
Your Ultimate Guide to Southwest Airlines Baggage Allowance

| How Many Bags Can You Carry On Southwest Airlines |
Step 1: Engage Your Inner Traveler - What Kind of Bags Do You Have?
Before we dive into the nitty-gritty, let's think about your packing style. Are you a minimalist, living out of a single backpack? Or are you traveling with enough gear to outfit a small expedition? Knowing your typical travel habits will help you understand which baggage categories apply to you most.
Southwest Airlines generally categorizes baggage into two main types:
Carry-on Bags: These are the bags you bring with you into the aircraft cabin.
Checked Bags: These are the bags that are stored in the cargo hold of the aircraft.
Each of these has its own set of rules regarding size, weight, and, importantly, fees.
Step 2: Mastering the Art of Carry-On: What Stays with You?
Southwest's carry-on policy is designed for convenience, allowing you to keep essential items close at hand.
2.1: Your Free Carry-On Bag
Every passenger on Southwest Airlines is permitted to bring one carry-on bag onto the aircraft, free of charge.
Dimensions are Key: Your carry-on bag must not exceed 24 x 16 x 10 inches (61 x 40 x 25 cm), including handles and wheels. It needs to fit comfortably in the overhead bin.
Weight Limit? Not for Carry-Ons! One of the fantastic perks of Southwest is that there's no specified weight limit for carry-on bags. However, you must be able to lift it into the overhead bin unassisted. If you can't, it might be too heavy!
2.2: Your Personal Item: The Under-Seat Companion
In addition to your carry-on bag, you can also bring one small personal item, fee-free. This is perfect for essentials you want right at your feet.
Snug Fit Under the Seat: Your personal item must fit under the seat in front of you. Common personal items include:
A purse
A briefcase
A laptop bag
A small backpack
A camera bag
Personal Item Dimensions: The maximum dimensions for a personal item are typically 18.5 x 8.5 x 13.5 inches (47 x 22 x 34 cm).
What Doesn't Count: Certain items don't count towards your "one-bag plus one personal-type item" limit. These include:
A child restraint device (for a ticketed child or if space allows)
Assistive/mobility devices for individuals with disabilities (no limit!)
Outer garments or other wearable articles of clothing
Food for consumption during flight (in disposable packaging)
Walking canes or umbrellas
Step 3: Navigating Checked Baggage: What Goes Below Deck?
This is where Southwest historically shone, but it's crucial to be aware of the recent changes to their policy.
3.1: The New Reality of Free Checked Bags
Tip: Every word counts — don’t skip too much.
As of May 28, 2025, Southwest Airlines has eliminated the universal "Bags Fly Free" policy for most passengers.
First Checked Bag: For most passengers, your first checked bag will now cost $35.
Second Checked Bag: Your second checked bag will cost $45.
3 or More Bags: If you need to check a third bag or more, the fee increases significantly to $150 per bag.
3.2: Standard Size and Weight Limits for Checked Bags
Even with the new fees, your checked bags still need to adhere to specific limits to avoid additional charges.
Weight Limit: Each checked bag can weigh up to 50 pounds (23 kg).
Size Limit: Each checked bag must not exceed 62 linear inches (length + width + height), including handles and wheels. Make sure to measure your bag accurately!
3.3: Who Still Gets Free Checked Bags? (The Exceptions!)
While the "Bags Fly Free" policy has largely changed, there are some important exceptions:
Business Select/Choice Extra Fares: Passengers who book these higher fare types will still receive two free checked bags.
A-List Preferred Members: Rapid Rewards A-List Preferred members get two free checked bags.
A-List Members: Rapid Rewards A-List members receive one free checked bag.
Southwest Rapid Rewards Credit Card Holders: Many co-branded Southwest credit cards offer one free checked bag. Check your specific card benefits!
Active U.S. Military Personnel and Dependents: Active duty military personnel (with valid ID) are exempt from checked, overweight, or oversized bag fees, provided each bag does not exceed 100 pounds and 80 inches.
Step 4: Understanding Additional Fees: When Do You Pay More?
Beyond the standard baggage fees, you might incur extra charges if your bags are too heavy, too large, or if you bring specialized items.
4.1: Overweight Baggage Fees
If your checked bag exceeds the standard 50-pound weight limit, you'll face an overweight fee.
51 to 70 pounds (24 to 32 kg): A fee of $100 per bag applies.
71 to 100 pounds (33 to 45 kg): A fee of $125 per bag applies.
Bags exceeding 100 pounds (45 kg) will generally NOT be accepted as checked baggage and may need to be shipped as cargo.
4.2: Oversized Baggage Fees
If your checked bag is larger than the 62 linear inches limit, an oversized fee will apply.
63 to 80 linear inches (160 to 203 cm): A fee of $125 per bag applies.
Bags greater than 80 linear inches (203 cm) will generally NOT be accepted as checked baggage.
Important Note: If a bag is both overweight AND oversized, only one fee will be charged, whichever is higher, as long as it doesn't exceed 100 lbs or 80 inches.
Step 5: Special Items and Sports Equipment: Your Unique Gear
Traveling with golf clubs, skis, or a musical instrument? Southwest has specific policies for these items.
5.1: Sports Equipment
Tip: Break down complex paragraphs step by step.

Many common sports equipment items can be checked as part of your baggage allowance. They count as one piece of checked baggage.
Standard Size and Weight Rules Apply: If your sports equipment (e.g., golf bags, skis, fishing equipment) is within the 50 lbs and 62 linear inches limit, it will count as one of your checked bags and the applicable fee will apply (or be free if you're in one of the exempted categories).
Oversized/Overweight Sports Equipment: If your sports equipment exceeds these limits, it will be subject to the standard overweight or oversized fees mentioned above.
Specific Items with Special Rules: Some items, like surfboards, might have specific fees or limitations. Always check Southwest's official website or contact them directly for the most current information regarding your specific sports equipment.
5.2: Musical Instruments
Musical instruments are handled with care on Southwest.
Carry-on Option: Smaller instruments (like guitars, violins) that fit in the overhead bin or under the seat can be carried on, provided they adhere to the carry-on dimensions.
Checked Baggage Option: Larger instruments can be checked as baggage, subject to standard checked baggage, oversized, or overweight fees. Southwest generally recommends proper packaging for instruments.
Purchasing a Seat: For very large or fragile instruments, you may also have the option to purchase an additional seat for your instrument, if it meets certain size and weight requirements.
Step 6: Pre-Flight Preparations: Packing Smart & Avoiding Surprises
Now that you know the rules, here are some actionable tips to ensure a smooth travel day.
6.1: Invest in a Luggage Scale
This is your secret weapon! A small, portable luggage scale can save you significant money and stress at the airport. Weigh your checked bags before you leave for the airport to ensure they are under 50 pounds.
6.2: Measure Your Bags
Don't eyeball it! Use a tape measure to confirm your carry-on and personal item meet Southwest's dimensions. Remember to include handles and wheels in your measurements.
6.3: Consolidate When Possible
If you're close to the weight or size limit for a checked bag, consider if you can shift some items to your carry-on or personal item. This can be a game-changer for avoiding fees.
6.4: Know Your Status & Fare Type
If you're an A-List member, A-List Preferred, or a Rapid Rewards credit card holder, understand the baggage benefits associated with your status or card. This could mean free checked bags where others now pay.
6.5: Pack Smart for Security
Remember TSA regulations for liquids, gels, and aerosols in your carry-on. Pack electronics where they are easily accessible for security screening.
Tip: Break it down — section by section.
Step 7: At the Airport: Check-In and Beyond
Even with perfect packing, the airport process still needs your attention.
7.1: Self-Tagging Kiosks
At many airports, Southwest offers self-tagging kiosks. This can save you time! You can print your own bag tags and then drop them off with a Southwest employee.
7.2: When to Check Your Bags
Southwest generally recommends checking bags at least 45 minutes before your scheduled departure time. If you check them too close to departure, there's a risk they might not make it onto your flight.
7.3: Tracking Your Bags
Southwest offers digital bag tracking, which can give you peace of mind once your bags are checked. Ask an agent or check the Southwest app for details.
Conclusion: Travel Smart, Fly Southwest!
While Southwest's "Bags Fly Free" policy is largely a thing of the past for new bookings, understanding their current baggage rules is straightforward. By being mindful of the carry-on and personal item dimensions, checking your bag weights, and being aware of the new fees and exceptions, you can still enjoy the convenience and value that Southwest Airlines offers. Happy travels!
